De facto company: definition, risks and evidence

Updated March 29, 2026 - The de facto company or de facto company is not a social form that one voluntarily chooses with statutes. It is a legal qualification which can be retained when people have acted together as partners without having correctly formalized their company. In practice, it often appears in disputes.

Article 1832 of the Civil Code recalls the three pillars of the partnership contract:

• ▸contributions;
• ▸a joint enterprise with a view to sharing a profit or a saving;
• ▸participation in losses.

The Court of Cassation recalls that one cannot automatically deduce the intention to associate from a simple financial participation. The judgment of June 23, 2004 emphasizes the need to distinctly establish the cumulative elements of the company. The judgment of March 15, 2017 also recalls that a company created in fact is not to be confused with a joint venture company.

• ▸joint project operates without clear statutes;
• ▸sustainable pooling of resources and income;
• ▸operation of a multi-party activity without finalized legal organization;
• ▸conflict between partners at the time of sharing or debt.

• ▸dispute over the distribution of profits;
• ▸discussion of losses and debt;
• ▸difficulties of proof;
• ▸judicial reclassification of a relationship that the parties thought was informal.
